I don't know, because there's an unforgiving goalpost lodged in the middle of the field?

And why is that goalpost lodged where it is? Well, that's just how they do things in Canada. In the NFL, the field goalpost(s) used to be at the goal line but for safety reasons, was moved to the back of the end zone in 1974. In Canada, though, the end zone is 20 yards deep, which would make many field-goal attempts prohibitively long.
